Joomla users and extension developers are asked to download and install the packages in order to provide quality assurance for the forthcoming 4.0 and 3.10 releases.
Joomla! 4 is the latest major release of Joomla! CMS. Please note that going from 3.9 to 4.0 is a migration. You would need to upgrade your J3.9 to J3.10, which will be available the day J4.0 is stable. J3.10 has a compatibility checker to help guide you through the migration to J4.0. Please do not upgrade any of your production sites to the release candidate version!
What is this release for?
Joomla 4.0 RC4 is aimed at extension and template developers. To encourage them to work with this release in order to prepare extensions for the stable release of Joomla! CMS 4.0. Users are encouraged to test the package for issues and to report issues in the Joomla! CMS Issue Tracker. Test sites based on this release candidate can be taken through to stable but never use this version on a production site. There will be an upgrade path between release candidates and the final release candidate to the stable of Joomla 4.0 should you wish to try a new site build.
Spotlight on Joomla4Speed
When in competition with other sites and your visitors' attention it's important to make sure your site has the best performance possible. You put all the hard effort into excellent articles, great design so you need a blisteringly fast CMS to deliver that crafted content. With Joomla 4 and a good hosting provider you get lightning speed as measured by the main independent arbitrator in such matters: Google Lighthouse
To test the speed and performance of Joomla 4 we used our global platinum sponsors, Scalahostings cloud VPS solutions and Rochen hosting. With default install of both CMS and hosting package we scored an impressive 100% for Performance. You cannot get better than that and all without customisation or fine tuning.
So why not test your own site with Google lighthouse? If your results are less than in the green with scores below that 100% then it's time to migrate to Joomla 4 and see the visitor and page ranking boost your site deserves. Joomla4Speed
How will Joomla 4 also benefit me?
Running a site with state of the art well written code helps you stay ahead when it comes to security. With many architecture changes designed to maximize security and keep hackers out, you can be assured that moving to Joomla 4 is a wise choice. The benefits are countless when it comes to ensuring you and your clients data are as well protected as they can be.
Whatever size your site is, accessibility is a must, and from the start Joomla 4 delivers best in class accessibility. The layout, contrast and infrastructure all have accessibility built in so all your visitors will benefit. We have aimed for W3C Accessibility Guidelines (WCAG) 2.0 (with AA compliance)
Workflows help you to run your site efficiently, making sure that the jobs that need to get done are done and by the right people. Combined with the many improvements in the media manager, content writers will love the new workflow and media manager.
Deliver customised emails that welcome and inform your website's audience effectively! With the new email template system it's easier than ever to make the emails your site sends be on message and on brand. Now you can take your site to the next level when communicating with your customers.
Search is a boost to any site. It allows your visitors to hone in on the areas they are interested in, increasing engagement and improving your sites ranking. So when it comes to search look no further, Joomla 4 smart search has many improvements over previous Joomla search and is the best to date.

Joomla 3.10 helps with the transition to Joomla 4
Along with Joomla 4 RC4, we are releasing the ninth alpha version of Joomla 3.10.
Joomla 3.10 is the bridge between the 2 major series. Joomla 3.10 stable will primarily be a release containing backports of API changes from the Joomla 4.0 development branch to help ease the transition to the next major release for the community. Joomla 3.10 will be supported for 2 years after it has been finally released.
Once your website is updated to 3.10, the pre-update checker will allow you to check the compatibility with the Joomla 4.0 minimum requirements in terms of the current hosting environment and, more importantly, your installed extensions. This will help you migrate to Joomla 4.0 smoothly.
Can I update my website from 3.9.x to Joomla 4 RC4?
The simple answer here is yes. Not on a production site of course, but if you want to test the update to Joomla 4, now you can.
In order to upgrade from 3.9.x to Joomla 4, you have to go via the latest 3.10 release. There is no direct upgrade path between 3.9 and 4.x planned nor supported. All upgrades go via 3.10.
For the upgrade please follow these steps:
- Go to the Joomla Update Component Options and switch the Update Channel to “Testing” and the Minimum Stability option to “Alpha”.
- Update to the latest 3.10 alpha using the Joomla Update Component.
- Switch the Update Channel to “Custom URL” and set the Custom URL to “https://update.joomla.org/core/test/310to4_list.xml”
- Now you get, update to the latest 4.0 Release Candidate.
- Please carefully check the results from the pre-update checker in terms of your environment and your installed extensions before upgrading.
- After the upgrade please switch back to the “Testing” Update Channel with the “Release Candidate” minimum stability to get future updates between Joomla 4 RCs.
If you need more details on the upgrade process you can find them in the documentation.

There are a variety of ways in which you can get actively involved with Joomla. It doesn't matter if you are a coder, an integrator, or a user of Joomla. You can contact any of our volunteer engagement team to get more information, or if you are ready you can jump right into the Joomla! Bug Squad.
The Joomla!

A great way for increasing your working knowledge of the Joomla! code base, and also a great way to meet new people from all around the world.
